Sorry I've not gotten to this.

This doesn't seem like the right fix... this is something that I think I got fundamentally wrong in r177055, and I spot by inspection numerous related mini bugs that aren't being triggered.

For example, why doesn't this happen for stores as well? If they're not sharing the same broken logic, why not? I'll try to carve out time to specifically debug this problem, but I fear the fix is going to be a bit more involved than this.
